DECEMBER 2013 ISSUE _ excellent results of operations _ energy Saving Simple and eﬀective _ oﬀshore Sierra leone
Welcome to another winter edition of the Crow’s Nest. It’s the festive season and it is of some comfort to notice that the downward trend of the industry has seemingly come to an end. The bulk markets have shown remarkable signs of recovery and the container markets are moving sideways for the time being, with prices for second hand tonnage and new builds already on the rise. Whilst this is nothing (not yet ...) to write home about, the year 2013 has been a very active one for the Thomas Schulte Group. Most noteworthy are the results of an Independent Business Review carried out this year. It conﬁrms that the Thomas Schulte Group is a highly efficient manager that has outperformed its peer group with substantial savings on the Opex cost, whilst operating under an elaborate quality management system. Considering the fact that the peer group disposes over substantially larger ﬂeets it also puts an end to the myth the efficiency is merely a result of scale. It is a result of a business philosophy carried out by a highly proﬁcient team of professionals. Concurrently we have continued to put into place measures that aim to increase the competitive edge of the fleet under management. The percentage of employment coverage of the ﬂeet seems to indicate that our efforts are paying off. I would like to express my sincere dedication to the entire crew on board the ﬂeet as well as our staff ashore, for their continuous support and valued input and wish all a Merry Christmas time and a happy and prosperous new year.

The shipping industry has traditionally set up rules and layouts for vessel lashing systems based on the requirements of the stormy North Atlantic. Therefore, the resultant stowage potential for other routes less affected by high wave and wind loads is not fully utilised. By combining long-term, statistical wave data with advanced computations and by considering current market developments, the class society Germanischer Lloyd SE has implemented Route Speciﬁc Container Stowage rules for sea lanes that have weather conditions that are more favourable.

Finally, a port agent in Mexico was appointed. No sooner said than done: CMA CGM ROSE deviated her course to the island of Tahiti. Upon the arrival of CMA CGM ROSE in Papeete, the local agent was already waiting on the pier. The Chief Officer disembarked, accompanied by the shipâ€™s medical crew, and was immediately taken to the next doctor. As soon as the medical crew was back onboard, the ship set sail again. CMA CGM ROSE arrived in Ensenada with a delay of less than two days. In port, the replacement Chief Officer was already waiting.

In the meantime, the surgery had been successful and the Chief Officer was on the mend. Today he is sailing again onboard a ship in the Thomas Schulte fleet.

The transhipment installations are located here, one within the inner anchorage and the other further outside. A big floating offshore transhipment platform is geared to discharge cargo from the large river barges. The barges come alongside the offshore terminal, which is capable to load huge quantities per London Mining acquired domestic haul roads and doubled

SMALL MiSTAKe, Big iMpACT The emergency response team was called after a crane driver attempted to shift a tank-container filled with olefin sulphide onto a truck and failed. During discharging operations of LiSA SChULTe at the port of houston, Texas the container collided with the trailer causing a tank valve rupture.
SMALL MISTAkE, BIG IMPACT
Olefin sulphide is toxic if inhaled. The dangerous cargo leaked out on the pier next to the ship. The stevedores alerted the port emergency response brigades immediately, arriving on scene quickly within 10 minutes. Dangerous cargoes for many industrial purposes are continuously shipped by container ships around the globe. The harm potential for health is often significantly high, so that uncontrollable reactions have to be prevented by all means along the transport chain. Packing and stowage of the cargoes is strictly regulated to ensure appropriate isolation according to the hazardous chemical, physical or biological character of the substance. However, handling dangerous goods containers during loading and discharging from the ship is a particularly delicate task. The protective packaging must not be damaged. The area on the pier near LISA SCHULTE was cordoned off. All persons were evacuated. The shipâ€™s crew found safe shelter inside the accommodation, shutting down the external ventilation. A shore emergency response team with chemical protection suits and breathing protection absorbed the spilt cargo later on and filled it into another tank. The whole area was cleaned up. Only after a careful check of the atmosphere, was the place confirmed to be safe. Regular operations continued. Thanks to the quick and efficient intervention of the crew and shore personnel, exposure to poisonous fumes was avoided and fortunately no one was injured.
